The Plex/Jellyfin/Emby/chat auto-login page JS (sso-gate.js
buildLoginPage) calls /api/auth/totp/check-session — the pre-1.5.0
legacy prefix. The back-compat shim in app.js only handled
/api/auth/gate/ and /api/auth/app-token/, so check-session 404'd and
the page hung at "Signing in to Plex..." forever (user reported
2026-07-09, confirmed: request returns "Route GET /v1/auth/totp/
check-session not found").
Add /api/auth/totp/check-session to the legacy path rewrite so the JS
gets the canonical /api/v1/totp/check-session endpoint.
Verified: plex.sami/dashcaddy-login now returns the auto-login page
and the JS check-session fetch resolves to {"authenticated":true} for
active TOTP sessions.
